78644466 ÷ 345 
Our goal is to divide 78644466 by 345.

Advancing to step 1:
When dividing 7 by 345, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 345

Let's proceed to step 2:
345 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 345

Let's proceed to step 3:
345 goes into 786 2 times with a remainder of 96.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 690 from 786 leaves us with 96.
Grab the next digit (4) from the dividend, add it to 96, then carry on: 964 / 345

Advancing to step 4:
The number 345 fits into 964 2 times, leaving a remainder of 274.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtracting 690 from 964 leaves us with 274.
Bring next digit (4) of the dividend behind the 274 and repeat the process: 2744 / 345

On to step 5:
345 goes into 2744 7 times with a remainder of 329.
Use 7 as the next digit of our solution. 
Result so far: 227.0
Deduct 2415 from 2744 and we're left with 329.
Append the next digit (4) from the dividend to 329 and continue with: 3294 / 345

On to step 6:
If we divide 3294 by 345, we get 9 and a remainder of 189.
Use 9 as the next digit of our solution. 
Result so far: 2279.0
If we subtract 3105 from 3294, we get 189.
Include the next digit (6) from the dividend after 189, then repeat: 1896 / 345

Step 7:
If we divide 1896 by 345, we get 5 and a remainder of 171.
The next digit of our result is 5. 
Result so far: 22795.0
The remainder is 171 after subtracting 1725 from 1896.
Fetch the next digit (6) from the dividend, attach it to 171 and continue: 1716 / 345

Going ahead to step 8:
When dividing 1716 by 345, we get 4 with a remainder of 336.
Write down 4 as next digit of the result. 
Result so far: 227954.0
Subtract 1380 from 1716 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 9:
If we divide 3360 by 345, we get 9 and a remainder of 255.
Write down 9 as next digit of the result. 
Result so far: 227954.9
If we subtract 3105 from 3360, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 10:
345 can be fit into 2550 7 times, resulting in a remainder of 135.
Record the quotient 7 as the next digit in the result. 
Result so far: 227954.97
Subtracting 2415 from 2550 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 11:
1350 divided by 345 is 3 with a remainder of 315.
Write down 3 as next digit of the result. 
Result so far: 227954.973
Subtract 1035 from 1350 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 12:
If we divide 3150 by 345, we get 9 and a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 227954.9739
If we subtract 3105 from 3150, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
345 can be fit into 450 1 times, resulting in a remainder of 105.
Record the quotient 1 as the next digit in the result. 
Result so far: 227954.97391
If we subtract 345 from 450, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 14:
345 goes into 1050 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 227954.973913
If we subtract 1035 from 1050, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 15:
If we divide 150 by 345, we get 0 and a remainder of 150.
The next digit of our result is 0. 
Result so far: 227954.973913
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 16:
345 goes into 1500 4 times with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 227954.97391304
Subtracting 1380 from 1500 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 227954.97391304, and the remainder is 1.2e-07.
